Realtek audio issues on OpenBSD 5.2

view story

http://unix.stackexchange.com – I am running OpenBSD/amd64 5.2 stable on a new machine, using a gigabyte motherboard with a realtek alc898 audio chipset. When I try to play any audio (sources include mpd, aucat, and cat > /dev/audio), I always end up with the system playing a grinding sound, not quite the same as white noise. I have been able to get the system to play audio under other operating systems, so the hardware is not at fault. Following the FAQ, audioctl and mixerctl are not muted and are at reasonable volumes. Following the debugging instructions gave the following: $ cat > /dev/audio < /dev/zero & (HowTos)
